1. Dia (Diameter): The "Dia" refers to the size of the RFID tag. In this case, it's 45mm in diameter, indicating it's likely a circular tag. This could be useful for applications where a compact size is necessary, such as animal tracking, asset management, or industrial applications.

2. LF (Low Frequency): LF RFID operates in the 125 kHz or 134 kHz frequency range. LF RFID tags typically have a shorter read range (up to a few centimeters to a meter), making them suitable for applications like access control, livestock tracking, or tool management. LF RFID tags are less susceptible to interference from water and metal compared to high-frequency (HF) or ultra-high-frequency (UHF) tags.

3. RFID (Radio Frequency Identification): This refers to the technology used for identifying and tracking objects via radio waves. RFID tags contain a microchip and an antenna to store and transmit data when they come into contact with an RFID reader. The tag is either passive (without a battery, activated by the reader) or active (with a battery for a longer read range).

Applications of Dia 45mm LF RFID tags

• Animal tracking (such as for cattle or pets)
• Access control systems for securing entry points
• Asset management in environments like warehouses or factories
• Inventory management in industries where metal or liquid interference is minimal but short-range precision is crucial
